…and I can’t believe I forgot about Hugh Laurie. Severely doable, that chap.
Me=33.
He’d be my first choice but he’s not old enough, dangit 
I have a half-brother older than him <sighs>
Based on what I remember:
Angie Dickinson
Barbara Billingsley
Betty Rubble, though I tap Willma in a pinch as well.
I know there are some serious Helen Mirren admirers on SDMB, and I know she looks great in a bikini still, but to me she’s a butterface. Just not attracted to her because of that.
Thank goodness, you didn’t say Pebbles. Because, that would be so, so wrong.
Teenage Pebbles, on the other hand…
And Teenage Bamm-Bamm, for that matter! Rrrowrrr…
Maggie Cheung (45)
Hey, she was quite the hottie as a teen!
All this Donald Sutherland lust is very encouraging to me, since he’s the celebrity that a number of people have said I look like in recent years.
Anyway, my pick: Lindsay Duncan, age 60. (I’m 44)
Looking great in the recent Dr Who Waters of Mars episode.
i don’t know. is it the hair? is it the idea of david bowie and what he used to be?
addendum - Kristen Scott Thomas.
Ha! Now that’s old. I’d do Betty too. David Bowie is still doable in my book. I’m 29.
Oh I forgot
Sorry to keep adding but the post edit times out rather too quickly for me
Lyndsy Wagner (sp) Bionic Chick, she was a tennis champion, but they had to rebuild her, with state-of-the-art transistors and relays and shit, probly DOS or Pascal, but she had a voice, that sounded like butterflies drizzled in butter and sugar, and a sandpaper gnarl.
Sting - age 58
Kevin Bacon - 52
Kevin Sorbo - 52
And Alan Rickman, who is in a class by himself.
Has Mary McDonnell been mentioned yet? She’s 57 and beautiful.
Ann-Margret
A damned fine choice, but my #1 has not been mentioned yet:
Emmylou Harris, 62
I’m 27
